Moq.Analyzers

Moq.Analyzers is a Roslyn analyzer that helps you to write unit tests using the popular Moq framework. Moq.Analyzers protects you from common mistakes and warns you if something is wrong with your Moq configuration.

Analyzer rules

• Moq1000: Sealed classes cannot be mocked
• Moq1001: Mocked interfaces cannot have constructor parameters
• Moq1002: Parameters provided into mock do not match any existing constructors
• Moq1100: Callback signature must match the signature of the mocked method
• Moq1101: SetupGet/SetupSet should be used for properties, not for methods
• Moq1200: Setup should be used only for overridable members
• Moq1201: Setup of async methods should use .ReturnsAsync instance instead of .Result
• Moq1300: Mock.As() should take interfaces

See docs/rules for full documentation.
